Create Backup Before File Modification

[r10r]

Hi @TomWright,

when I use dasel I like to create a backup if it modifies a file.

Currently I use cp before running dasel to create the backup.
But I would prefer that dasel takes care of it.
What about implementing the following (global) commandline flags ?

 -b, --backup                  create a backup before writing the file
 --backup-suffix string        suffix to use for backup file (default .~)

All of the modifying commands support a -o or --out flag that allows you to change where the modified contents are written. I expect this largely covers this need, would you agree?

[r10r]

Hmm, I'm unsure. How would you use the --out flag to modify a config file and create a backup within a single command?

[TomWright]

It's more that using the --out flag tells dasel to write the modified file to a new location.

So wouldn't the --backup flag would be a nice addition then ?

Yeah I think it could help
